I backported some changes from fedora-atomic master to f21:
https://git.fedorahosted.org/cgit/fedora-atomic.git/log/?h=f21
Here are 4 patches for spin-kickstarts master for fedora-cloud-atomic.ks. I tried to
actually test them against rawhide but hit
https://bugzilla.redhat.com/show_bug.cgi?id=1111290
So I backported them to f21 and then I hit a different (presumably anaconda, but maybe
dracut) bug where it loops forever at shutdown (haven't searched for/filed a bug
yet).
However if I terminated the VM in imagefactory, the resulting qcow2 works.
To save you all the pain of testing this until we get patches landed, please try:
